Hi,the patch from Andreas Krebbel (https://gcc.gnu.org/ml/gcc-patches/2014-02/msg00194.html) adds a prototype for __udiv_w_sdiv to longlong.h if needed.
This fixes a build failure of glibc on s390 31 bit.(see "Re: [PATCH] Turn implict-function-declaration warnings into errors", https://www.sourceware.org/ml/libc-alpha/2014-09/msg00264.html)
Please review Andreas Krebbel´s patch and give okay for commit. Bye Stefan
